When she woke up, Jiang Zhi, a doctor of agricultural science, became a little peasant girl on the road to escape from famine in ancient times. Good news: She has an entire knowledge base of modern agriculture in her head, from breeding to soil improvement, from pest control to agricultural product processing, everything! Bad news: Her family has only four walls, her father is dead and her mother is weak, her younger siblings are crying for food, she only has a handful of soil in her hand, and there are only three grasses in the ground. The neighbors looked at her like she was a fool and thought that a girl who was stupid at reading was useless. While everyone was still breaking their heads over a bite to eat, Jiang Zhi said silently: "Mom, plant ash and human and animal excrement are mixed together and fermented. This is called 'farmer manure', and its fertility is comparable to that of golden manure!" "Brother, this red-skinned wild fruit cannot be eaten, but its rhizome can. We call it 'potato'. It is not a dream to produce a thousand kilograms per acre!" "Listen to me, everyone, locusts are flying high-protein, deep-fried, crunchy, and the kids next door will make them cry!" The villagers first said: This eldest girl from the Jiang family is probably going crazy with hunger, because she makes mud and smelly things every day. Later: It smells so good! Following Jiang Yatou, everything that had no land to plant was cleared. Whatever you planted, you would get a good harvest, and whatever you raised, it would be full of crops. The poor mountain village that was once barren has been transformed into a land of plenty and plenty of food, which is well-known far and wide. One day, a handsome scholar passing by for a private visit in Weibo looked at the "Five-Year Agricultural Development Plan" in her hand and fell into deep thought. Scholar: "Girl, your slogan of 'scientific farming, industrial prosperity' is quite talented." Jiang Zhi wiped his sweat and picked up the hoe: "It's not bad, basic operations. Hey, scholar, don't just look at it.
